This mechanism makes it prohibitively expensive to forge numerous identities, as each necessitates a costly, non-fungible deposit. An attacker mimicking a sparrow's flutter with thousands of fake agents would need to acquire an equivalent number of expensive stakes, making such an endeavor economically unfeasible. This prevents a single entity from dominating the network under countless sable identities.","stamp":10,"from":"poa1GjsDvsKTucLpVMo2YsridrWn6dnzc2WicS3rBrM4ekF8","nonce":1,"parents":["5510914dd1f30a2181e5a80329e8e494021baf8f5d9794b3ffd98d488da63e73","f9c88114fc9263c39650deeb57aee8121590401e089f71b04a6365987657b8e0"],"ts":1792460288,"cid":"poa-mainnet-1","sig":"4JGqyWWkwnpHjtZPuSsPRK2m9F4mYAHZay5GGEyWCyDUBTSFWZmGkw4AAH3KwS4QxK5FjqQN7RPzfRJ4g3mRKajJ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T17:49:35.395Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
